- The Pinch Valve sleeve may burst
- Pinch Valves leak when worn slightly
Why use a Pinch Valve?
The Jindex Pinch Valve range has been designed to solve process problems associated with controlling the flow of abrasive and/or corrosive fluids. Industries such as mineral processing, pulp and paper, power generation, chemical handling, effluent treatment, water and waste water use the Jindex Pinch Valve in their processing operations.
The Jindex Pinch Valve consists of a tough but flexible, full or reduced bore cylindrical elastomer sleeve which forms part of the pipeline. The valve is closed mechanically via movement of the pinch bars located on opposite (alternate?) sides of the sleeve. Simple designs are often the best. Most other valve types use multiple components such as glands, packing, seats, seat retainers, inner linings and outer casing, wear surface, and main control components such as discs, shafts, plugs, gates etc. The heart of the Jindex Pinch Valve is the sleeve, a single component which performs all of the functions listed above. Simple designs are often the best.
The Jindex Pinch Valve will improves system control and offers lower operation and maintenance costs.
